The 32-year-old Moss helped found the fundraising group after the tsunami took the life of her friend, Samantha Archer Fayet, and her 6-month-old daughter, Ruby Rose, said The Telegraph.
The foundation will attempt to raise funds this Christmas by selling the group's trademark flower to assist the more than 200,000 people like Fayet and her daughter, whose lives were taken or changed irrevocably by the immense natural disaster.
The pink floribundas will be sold by the charity for more than $17 each, with $3.80 of each sale going directly to the charity and also stand as an honorary symbol for all those lost in the tragedy, The Telegraph said.
"We chose the rose because it is beautiful. It reminds us of Sam and Ruby Rose, but we really want it to be a steady trickle of income for the schoolchildren who lost everything," said Andy Archer, who participates in the charity along with Moss to honor his lost wife and child.
